Yang Yanding, General Manager of Dongfeng Motor's Strategic Planning Department (Brand Management Department) and Party Secretary of the R&D General Institute, stated at the conference that the enterprise, leveraging the "Rising Eastern Wind 2030" strategy released at the 2026 Beijing Auto Show, is implementing the "Sky-Clean Zero-Carbon" development plan, establishing hydrogen energy as a core strategic track, adhering to independent technology R&D and industrial self-reliance, and proactively shouldering the industry responsibility for green and low-carbon transformation of the automotive industry. Going forward, Dongfeng Motor plans to leverage the Hydrogen Energy Industry Innovation Alliance to collaborate with government agencies, upstream and downstream enterprises in the industry chain, research institutes, and scenario application parties to co-build a new hydrogen energy industry ecosystem featuring collaborative innovation, resource sharing, and scenario sharing.

Fuel cell durability is the core key determining whether hydrogen energy products can transition from demonstration pilots to large-scale commercial use, and has long been a core pain point constraining industry development. To break through the durability technology bottleneck, Dongfeng's R&D team independently built the "2-3-3" durability technology system, constructing a comprehensive and systematic stack durability assurance system from three major dimensions: core material optimization, extreme operating condition adaptation, and full-cycle aging control, enabling hydrogen power core components to handle various complex road conditions and extreme operating conditions including severe cold, extreme heat, bumps, heavy loads, and hill climbing, significantly improving equipment operational stability and service life.

In terms of core material upgrades, Dongfeng Motor innovatively adopted high-durability catalysts combined with anti-corrosion conductive dual-coating technology, fundamentally solving common problems such as aging and corrosion of stack core components, significantly improving parts durability and stability, with overall durability performance far exceeding national industry standards. For the complex operating conditions faced in long-haul commercial vehicle transportation such as dry-wet alternation, high-frequency vibration, and heavy-load hill climbing, the enterprise equipped three major protective technologies to comprehensively safeguard stable stack operation. Among them, membrane electrode stress control technology prevents core component stress damage; integrated vibration-resistant packaging technology secures internal parts, eliminating loosening and air leakage issues; the intelligent water-thermal management system dynamically adjusts internal water volume and temperature, effectively preventing equipment overheating and freezing faults, adapting to various extreme scenarios including deserts, plateaus, and icy conditions.

In terms of aging control, the equipment is equipped with high-precision stacking technology to ensure highly uniform voltage output of individual cells within the stack. It is also configured with an online rapid activation system and AI life prediction model, enabling real-time monitoring of stack operating status and intelligent health assessment, precisely predicting equipment maintenance cycles, achieving intelligent operation and maintenance management, and significantly reducing later operational failure risks. With comprehensive technological support, Dongfeng's 400kW fuel cell platform successfully obtained dual authoritative certifications from the HyTA Hydrogen Marathon, with its technical capabilities officially recognized by the industry.

Currently, Dongfeng Motor has completed construction of a full-chain independent hydrogen energy technology system covering core materials, key parts, system integration, and complete vehicle implementation, creating three major power stack platforms at 70kW, 150kW, and 400kW, fully covering hydrogen demand across all scenarios from 20kW to 400kW. Among them, the 400kW fuel cell system custom-designed for 49 mt heavy-duty hydrogen trucks can achieve ultra-low temperature cold start at -40°C, with a designed equipment lifespan of up to 30,000 hours, and was successfully selected as a Hubei Province 61020 landmark product, combining technological advancement with practical applicability.

The newly launched T1 Commercial Vehicle New Energy Platform focuses on the core needs of logistics industry users, optimizing and upgrading around four core pain points—energy consumption, vehicle weight, refueling, and safety—to create a "versatile, fast, reliable, and economical" new commercial hydrogen experience, providing quality solutions for the green and low-carbon transformation of long-haul logistics. In terms of energy consumption costs, the product underwent real-world testing across mountain and plain road conditions, achieving hydrogen consumption as low as 7 kg per 100 km, effectively reducing long-haul freight operating costs. In terms of auto body weight, the 49 mt hydrogen tractor weighs only 8.8 mt, basically flat with traditional gas-powered vehicles and outperforming most similar new energy car models on the market, helping users increase cargo capacity and reduce operational losses.

In terms of refueling and safety, the platform car models require only 15 minutes for hydrogen refueling, with a single-charge driving range of up to 1,700 km, completely eliminating refueling anxiety for long-haul freight. It is also equipped with an intelligent distributed power system and a 360-degree comprehensive safety protection system, successfully passing the European DEKRA Functional Safety C-level international high-standard certification for commercial vehicles, comprehensively ensuring safe and stable vehicle operation.
